Talkback Paging

168 025-9034AA

Narrative of a Talkback Page

Caller calls. Caller hears ringback (2 seconds on, 4 seconds off) while number is looked up

in database, and is identified as a talkback paging call.

The talkback count for the destination channel is checked, if there is room for another

talkback caller the count is incremented and the call proceeds. If the count is at or above

the options.cus file MaxTB threshold (default is 2, as was hard coded in V300) one of two

things happens:

1. If the caller has no forward programmed then the caller hears:

a. if the system has system voice prompts - “the system is busy, please call back

later”, followed by fast busy

b. if no system voice prompts then just fast busy

2. If the caller has a forward programmed then the call will be handled as if it were

for the second non-talkback mode.

If the phone number has a system or custom welcome prompt this is played to the caller. If

a security code is called for it will be processed. If a function code is called for it will be

processed.

If a voice message is specified it will be taken in the usual way, as per the database record.

The message cannot be insured, as talkback is a special case of paging mode.

If the terminal has system voice prompts, the caller will now hear either “your call is being

processed” if this call incremented the talkback count from 0 to 1, or “another call is in

progress, please wait” otherwise. If the subsequent caller has a higher priority they may

actually be processed first and the prompts will be inappropriate. Note also that if you

have system voice prompts, you can delete the “your call is being processed” prompt,

which will speed the processing of the talkback call.

The caller will hear ringback until the call is ready to be paged. If the caller enters DTMF

*2 during this ringback, and the subscriber has forward on no answer / system busy (a

second mode is programmed in the subscriber database record), then the forward will

happen immediately.

The talkback page will batch as per its priority, 1-4, N, or B (B does not mean a live voice

message in the talkback case, but will break through other non-breakthrough pages).

When the station card is ready to page the called pager, the caller will hear 0.3 second of 1

kHz tone. This is to indicate the call is really going on the air. Then ringback (4 seconds

off, 2 seconds on) is resumed.

The station card will send the page. If a voice message was taken, it will now be sent.

After the page, the station card will transmit ringout on the channel. The station card will

look for COR as an answer indication.
